Abstract (en)
[origin: EP0590861A2] This invention relates to methods for making a credit/debit card purchase without revealing the card number to the vendor (3) of services or goods. The card holder (1) is connected to a data base (5) and provides the card number, plus holder identity verification, to the data base. The data base then verifies whether the card holder is authorised to incur the expense of the purchase, and, if so, provides an authorisation indication or code to the vendor (3); the card number cannot be derived from the authorisation information, thus helping to preserve the secrecy of the card number. <IMAGE>
